Its not really wated money if your causing yourself liver/brain damage. DXM definately isn't good for you, rspecially high dose trips, but if low doses are done no more than once a month it smight be ok. You definately don't want to use cough medicines with other active ingrediants-some can be very damaging or even fatal at high doses.

Theres no point being stingey with money when your putting you brain and body at more risk than you need. You really just need weed and a few psychedelics-not harmful. But its not my job to preach, if you want to do that shit go ahead and do it.
